Craving the smell of gasoline?

I have always loved the way gas smells. I am not talking about huffing it or anything. It has always been such a pleasant smell to me. But lately it has been stronger. I can't get enough once I smell it, and I get the urge to go out of my way to go smell it. It smells so good it's like a mouth watering thing, but not like I want to drink it or anything lol. It just smells that good. What the heck is up with this?
